Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a joint strike against an hidden munitions depot in Syria used by the Daesh militant organization, according to the UK's MoD.
The site, located using intelligence, was assessed as containing munitions and bombs, the release indicated, and was located in hills just above the ancient city of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to strike a several approach shafts down to the site... early reports suggest the objective was successfully hit," the ministry announced.
There was no evidence of any harm to civilians in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager refuelling tanker.
IS - alternatively referred to as the so-called Islamic State - established militant control over large swathes of Iraq and Syria until 2019.
"This action underscores the UK's leading role, and commitment to stand shoulder to shoulder with allied nations, to eliminate any revival of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary John Healey said.
RAF aircraft have conducted surveillance missions over Syrian airspace to "forestall any attempted comeback" of Islamic State after its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank all the members of the UK armed forces involved in this mission for their professionalism and their bravery," the Defence Secretary added. "They were among thousands of British personnel stationed over the festive period. This mission, to eliminate dangerous terrorists who pose a risk to our safety, demonstrates how UK forces are always on standby, all year round, ensuring Britain's security at home and powerful internationally."
During December, the US military conducted what it described as a "massive strike" against IS targets in Syria, after an attack resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations reports Daesh still boasts an estimated 5,000 to 7,000 fighters in both countries.
